Is there any chance you will ever resolve any doc question on your own by not misusing this forum structurally as a free documentation lookup service?
Why can't you do anything on your own?
Why are you so lazy?

View for Last executed DDL ?

Hi,
Is thr any view to find out the last executed ddl ?
Because i need to know last change happend in the database .
Thanking You
Jeneesh

From asktom :
Tom,
Can I have my last executed SQL retrieved from the database?
just by passing the sid. I want those SQL executed in my application not the onse executed by
Oracle itself
Followup November 12, 2003 - 5pm US/Eastern:
you'll get the last sql executed by joining v$session to v$sql. if the last sql executed was
recursive SYS sql -- you'll get that (that would be the last sql). we really don't discriminate
between them
Forgot to tell you this data dictionary view will age out. So there is no absolute guarantee you will find all the sql executed since the database instance has been started. Other option is Audit. For more information refer oracle manual.

How to find last DML operation in oracle ADF

how to find last DML operation in oracle ADF
Please help me
Thanks
Damby

In the base EntityIml class, just override doDML() method as I said.
(see http://docs.oracle.com/cd/E16162_01/web.1112/e16182/appendix_mostcommon.htm
"Methods for Creating Your Own Layer of Framework Base Classes")
So, put a some flag in the session.
You should not call doDML() method in backing bean, it will be called by framework.
In the backing bean, you only have to get that information from the session, as follows:
String last_dml_op = (String)ADFContext.getCurrent().getSessionScope().get("last_dml_op");And voila...

Sir,how to find the last DML operations

Hi,
Please tell me how to find the last DML Operations at least minimum 30 queries.
Thanks in advance,

Shared Pool is a memory location in SGA that contains SQL Statement that are submitted to Oracle for execution. This area is common to the entire database. Its not specific to user.
So what ever Unique SQL statement that is submitted to the SQL Engine will be available here. Shared Pool has a size limit. That is defined by the parameters SHARED_POOL_SIZE and SHARED_POOL_RESERVED_SIZE. So when the Shared pool becomes full the data needs to be removed from it. That is done in FIFO basis.
Oracle provides a visibility to this area through dictionary view V$SQLAREA. So this view will not only contain the SQL executed by you but also by every one. Even the one executed by oracle itself.
So in my opinion what you are asking is not possible to get. You must have some logging mechanism in your application to get this information.

Anyone know of a good OLAP DML/DDL tutorial? (and NOT reference guide)

In addition to Analytic Workspace, I am trying to learn how to build cubes using just the OLAP DML / DDL language.
Oracle and others have published a great deal of reference material on the language of OLAP DML / DDL but I can't find any real tutorials that guide me logically thru the process of creating cubes and all that goes with it (defining dimensions, hierarchies, measures, calculations etc..) All the reference material is spread out in bits and pieces and difficult to efficiently learn from. Does anyone have any good OLAP DML / DDL tutorial links they could recommend? Thanks.

Thanks.This is a very difficult task. The OLAP DML/DDL only supports basic multidimensional variables, dimensions (very primitive), and relations. The externally visible cubes and dimensions are a construct of a lot of component objects (a dimension has many primitive dimensions and relations put together to create the higher level DIMENSION that goes with a cube; a cube has multiple variables and other pieces that get put together) in the AW, plus a bunch of metadata objects in the Oracle dictionary.
You really don't want to try to create your own and expect them to interact with the OLAPI interfaces. It is possible to construct your own version of things, but you'd also have to do your own view generation, etc. There are applications out there that are created from scratch, but they are completely from scratch (including whatever interactions they have via SQL). Whatever you create will not work with any of the Oracle-provided interfaces, nor the recently-announced Simba MDX package.

How to pull a last DML done on any table

Hi Gyans,
Is there a way for to pull the last DML done on any table, using normal sqlplus - if not then let me know the tool which you can use to do the same.

Have you gotten ora_rowscn to work ?
SQL> select scn_to_timestamp(max(ORA_ROWSCN)) from TABLE1;
SCN_TO_TIMESTAMP(MAX(ORA_ROWSCN))

SQL> insert into table1 values(8);
1 row created.
SQL> select scn_to_timestamp(max(ORA_ROWSCN)) from TABLE1;
SCN_TO_TIMESTAMP(MAX(ORA_ROWSCN))
22-SEP-08 01.13.30.000000000 PM

Any issue if we writing DML,DDL and TCL commands in stored functions.

Hi,
Is there any issue if we writing DML,DDL and TCL commands in stored function with help of PRAGMA AUTONOMOUS_TRANSACTION.

Hi,
Yes, Ofcourse. Using DML Statements Inside the function using PRAGMA AUTONOMOUS_TRANSACTION is not highly
recommended. It is recommended to use AUTONOMOUS TRANSACTION for error logging purposes only, and
when used in an disorganized way it may lead to dead locks and we will have problem when examining the
Trace Files.

Reg. Extracting DML/ DDL Stmnts.

hi ,
I dont have access to Db . So I apologise straight away for not trying out the code myself to interpret and scrutinise.
The code is to extract DML / DDL stmnts from all_procedures. and I have tried a sample (select stmnt) of it . Please let me know if its wrong or working fine.
create or replace procedure sp_identify_stmnts (i_table in varchar2)
is
i_text varchar2(32767);
begin
select REGEXP_SUBSTR(replace(text,chr(10)),'select+;$',1,1000,'i') into i_text from ALL_PROCEDURES where
PROCEDURE_NAME=i_table ;
dbms_output.put_line('text is ' || i_text);
end;
/Oracle 10g release 2

It won't work, because ALL_PROCEDURES has no TEXT column with code.
I think you have to use something like this:
select text
from all_source
where type='PROCEDURE'
and owner=:proc_owner
and name=:proc_name
order by line -- code is splittet in multiple lines
;

Last update DDL time of column

Hi,
Requirement: when the column of the table got updated.
I have tried to use following query but my Oracle9i Enterprise Edition Release 9.2.0.8.0 does not support ORA_ROWSCN.
SELECT SCN_TO_TIMESTAMP(ORA_ROWSCN) from FOLDERHEADERS;I need to know when folders.notify column got updated last time.
select *
from folders
where notify is not null
where dept = 10;Thanks
Sandhya

Since you are using Oracle 9.2, if you don't have something that tracks updates (i.e. a LAST_UPDATED_TIME column in the table, an audit trail, etc.), you're probably out of luck. Oracle doesn't track that information.
If you're really desperate and your database is in ARCHIVELOG mode and you have all the archived log files from the days when the modification could have been made, you could potentially use LogMiner to read through the redo logs looking for changes of interest. This would be very slow and likely very manual so it would not be appropriate to do from an application. But it could be done if you're trying to track down a one-off issue.

Note that your subject line refers to DDL but the text of your question appears to relate to DML changes. I assumed the latter (DML tracking) was the actual goal. If you're tracking DDL, that is tracked at the table level in the LAST_DDL_TIME column in DBA_OBJECTS but not at the column level. Again, you could use LogMiner to look for this sort of thing if you aren't auditing the change but doing so would be labor intensive.

Tool to do syntax check on DML/DDL

Is there any tool in Toad or SQL Plus or any other IDE to do a syntax check on DDL/DML statements without executing them ?

In my Toad Verson 7.6, there is a built in formatter namely -> Formatter Plus v4.8.0. This will format any given SQL Statement/ PL/SQL Code.
Also if your statement is wrong syntactically, the formatter will throw an error.
You just have to type the code and right click -> Formatting Tools -> Format Code. Alas your code gets formatted neatly!!
Thanks,

Undo tablespace/redo logs/ DML /DDL/ truncate/ delete

1st scenario:Delete
10 rows in a table
Delete 5 rows
5 rows in the table
savepoint sp1
Delete 3 rows
2 rows in the table
rollback to savepoint sp1
5 rows in the table
So all DML affected values are noted in the undotablespace and present in the undotablespace until a commit is issued.And also redo logs make note of DML statements.AM I RIGHT??????
2nd scenario-truncate
10 rows in table
savepoint sp1
truncate
0 rows in table
rollback to savepoint sp1 gives this error
ORA-01086: savepoint 'SP2' never established
So is truncate [are all DDL statements] noted in the undo tablespace and are they noted in the redologs????????
I KNOW THAT A DML IS NOT AUTOCOMMIT AND A DDL IS AN AUTOCOMMIT

When you issue a delete is the data really deleted ?WHen you issue a delete, there is a before image of the data recorded to the undo area. (And that undo information itself is forwarded to the redo.) Then the data is actually deleted from the 'current' block as represented in memory.
Therefore, the data is actually deleted, but can be recovered by rolling back until a commit occurs.
It can also be recovered using flashback techniques which simply rebuild from the undo.
When you issue a truncate is the data really deleted
or is the high water mark pointer for a datablock lost?The data is not deleted. Therefore there is no undo record of the data 'removal' to be rolled back.
The high water mark pointer is reset. It's old value is in the undo, but the truncate is a DDL command, and it is preceded and followed by an implicit commit, voiding any potential rollback request.
I mean you can always rollback a delete and not
rollback a truncate?Correct - using standard techniques, deletes can be rolled back and truncates can not.

Best parameters setting for DML & DDL?

hi,
i am implementing the DDL & DML replication using OGG. i just wanted to know what should the best parameters for extract, data pump(source) & Replicate process(Target).
while my source and target having same structure.
& i have to replicate 277 tables.
thanks.

To improve the bulk DML operation via goldengate replication:
Using BATCHSQL
In default mode the Replicat process will apply SQL to the target database, one statement at a time. This often causes a performance bottleneck where the Replicat process cannot apply the changes quickly enough, compared to the rate at which the Extract process delivers the data. Despite configuring additional Replicat processes, performance may still be a problem.
Configuration Options
GoldenGate has addressed this issue through the use of the BATCHSQL Replicat configuration parameter. As the name implies, BATCHSQL organizes similar SQLs into batches and applies them all at once. The batches are assembled into arrays in a memory queue on the target database server, ready to be applied.
Similar SQL statements would be those that perform a specific operation type (insert, update, or delete) against the same target table, having the same column list. For example, multiple inserts into table A would be in a different batch from inserts into table B, as would updates on table A or B. Furthermore, referential constraints are considered by GoldenGate where dependant transactions in different batches are executed first, depicting the order in which batches are executed. Despite the referential integrity constraints, BATCHSQL can increase Replicat performance significantly.

DML DDL Message

Hello Expert,
In My application when users press the “Run” it is executing the DML or DDL statement. What I am looking for it is to display the message that’s come after executing this statement. I am want the same message which appear when you run the DML or DDL statement from SQL command prompt: For example
SQL> Create table xyx (a varchar2(1))
Table created. --- {color:#ff0000}"I want to display this message on my application"{color}
SQL> Drop table xyx
Table dropped. --- {color:#ff0000}"I want to display this message on my application"{color}
SQL> update tb_HR set firstname= 'SAGAR' where AGSNO = 2461059
0 row(s) updated. --- {color:#ff0000}"I want to display this message on my application"{color}
Hopefully my example will explain what I am looking for.
Sagar

Sagor,
Your submit process can use the success message to display whatever you want. Create hidden items or application level varaibles to hold the name of the object you are working with and form the message using them.
Keep Smiling,
